Summary: Feeding fiber and BCAA to sows during late gestation and lactation can improve litter weights at weaning. Supplementing primiparous sow diets with lucerne chaff may benefit their progeny performance, especially in terms of D21 weights. Additionally, the SIMLUC diet showed more effectiveness in improving the performance of primiparous sows compared to the control diet.

Summary: Newborn piglets have a high mortality rate associated with low birth weights and intra-uterine growth restriction. Nutritional strategies during gestation and assistance in the transition period can improve fetal development and increase piglet survival. Optimizing the farrowing environment, supervising and assisting newborn piglets, cross-fostering, providing nurse sows, and artificial milk are effective approaches to enhance piglet survival.

Summary: Weaning piglets often suffer from severe diarrhea and intestinal motility disorders. This study found that the increased slow-wave frequency and decreased c-kit expression in the intestinal longitudinal muscle-myenteric plexus (LM-MP) may be associated with postweaning diarrhea (PWD). The weaning process also caused inflammation, oxidative stress, and DNA damage in the LM-MP, leading to cell cycle arrest and inhibited cell proliferation in the ileal and colonic LM-MP. This ultimately impairs intestinal motility regulation and results in diarrhea in piglets.

Summary: Gallic acid supplementation in weaned piglets' diet improves growth performance, especially for low weaning weight piglets, and reduces diarrhea incidence. Additionally, it enhances plasma antioxidant status, leading to better overall health outcomes for the piglets.

Summary: Maternal VD3 supplementation during gestation can improve intestinal health and microbiota in suckling piglets, including increasing the length and height of intestinal villi, enhancing the expression levels of intestinal protective proteins, and increasing the abundance of beneficial bacteria and the content of probiotics in the intestine.

Summary: This study analyzed the differences in gut microbial structures and fecal metabolic profile between post-weaning diarrhea and healthy Chinese Wannan Black pigs using 16S rRNA gene sequencing and LC/MS-based metabolomics. The results revealed an increase in the relative abundance of the bacterial genus Campylobacter and a decrease in phylum Bacteroidetes and the species Streptococcus gallolyticus subsp. macedonicus in piglet diarrhea. Significant changes in the fecal metabolic profile, particularly higher levels of polyamines (spermine and spermidine), were also detected in diarrheic piglets. Furthermore, there were substantial associations between the disturbed gut microbiota and the altered fecal metabolites, especially a strong positive relationship between spermidine and Campylobacter.

Summary: The study aimed to assess the effects of dietary supplementation of microencapsulated L. acidophilus and L. plantarum, individually or in combination, on various aspects of weaned piglets, including growth performance, organ development, diarrhoea incidences, blood profiles, intestinal histomorphology, and microflora. The results showed that the supplementation of probiotics increased feed intake and decreased diarrhoea incidence, while the combination of L. acidophilus and L. plantarum had the most beneficial effects on intestinal morphology and microbial populations.

Summary: Early weaning is important for improving sow production efficiency, but often leads to postweaning diarrhea (PWD) in piglets. Traditional antibiotic supplementation has drawbacks, while probiotics have shown potential for preventing and treating PWD by regulating intestinal barriers.

Summary: Weaning and the following two months pose significant risks to a pig's gastrointestinal health. The change in diet and accelerated intestinal maturation can lead to digestion and absorption issues, causing diarrhea. Antibiotics are no longer effective in resolving these problems, so finding a balance between intestinal health and growth becomes crucial. This study evaluated the impact of dietary protein levels on piglet growth and post-weaning diarrhea (PWD) incidence, finding that a low protein diet reduced PWD while minimally affecting growth parameters.

Summary: The results of this study indicate that dietary supplementation with Forsythia suspensa extract can improve litter birth weight, colostrum fat and protein contents, nutrient digestibility, antioxidant status, immunoglobulin, inflammatory cytokines in sows and newborn piglets. Moreover, FSE could also potentially modulate reproductive hormones in sows.

Summary: The study evaluated the effects of tannic acid on growth performance, diarrhea rate, nutrient digestibility, and intestinal health in weaned piglets. Results showed that appropriate supplementation of tannic acid can prevent post-weaning diarrhea and improve intestinal health of piglets.

Summary: The study aimed to investigate the impact of early socialization and an enriched neonatal environment on the adaptation of piglets to weaning. Post-weaning differences in microbial colonization, metabolic response, and gene expression were observed between piglets raised in barren vs enriched environments, indicating a possible link between environmental enrichment and improved adaptability to weaning stress.

Summary: Zinc oxide (ZnO) supplementation at pharmacological doses is widely used in post-weaning piglets to manage post-weaning diarrhea (PWD), which causes significant economic losses in the most crucial phase of a piglet's production cycle. ZnO exerts various positive effects throughout the gastrointestinal tract through multiple mechanisms, targeting intestinal structure, digestion, antioxidants, and immunity. However, concerns over environmental impact and emerging threats are challenging the sustainability of ZnO's extensive utilization.

Summary: Maternal supplementation of fish oil during late pregnancy and lactation significantly promotes growth, enhances immunity, and reduces post-weaning diarrhea in piglets, which may be partially due to the altered gut microbial community.
